What I was thinking (in my limited head on these things) was more along the lines of a holding pool, that could have contracts placed upon it for a portion of the tokens, so they would be able to be used for staking purposes, whilst still being held behind owner keys in some way. kind of like an escrow?
I have no idea if this is useful or even possible.
I was also wondering if it could be used to stabilize HBD directly in some way using its value. But I can't get my head around that one.
